Gas planets

Ive been wondering about this for a while. i read in the newspaper about jupiters new red spot, but anyways they mentioned that it was a gas planet. does this mean that if you were to fly to jupiter and keep going, eventually you'd go right through it and out the other side? or is it so dense that the gas turns into a solid at the center?

so, if you lit a match on a planet that was made out of flammable gas, it would just disappear? wow that sucks

Stop and think about what you just said.

First consider what 'burning' actually means(A chemical reaction between an oxidizer, of which there would be very little on jupiter, and a reactant, of which there is plenty in the form of hydrogen). Next consider that matter has to be conserved(so it doesn't make sense to talk about anything just 'disappearing').

As russ said:

Hydrogen requires oxygen to burn and there is very little of that on Jupiter.

Remember, Jupiter was hit by a comet (broken into many fragments) that exploded with an energy greater than all the nuclear weapons on earth combined, and it is still there.

BTW, if you DID fly your spaceship into Jupiter, you would never get anywhere near the metallic core. Pressures climb into the hundreds or even thousands of atmospheres long before that. There is speculation that it is one continuous gradient from gas to liquid to solid.

We know there is a solid metalic core because it has a strong,- very very, very strong magnetic field which makes big radiation belts around it.
And you could even get past a few of Jupiter's moons without this radiation zapping you to bits.
